Pajic, @gokcumenlab.bsky.social @spit-lab.bsky.social et al. explored the evolution of saliva-related SCPP genes, observing extensive diversification of SCPP genes within mammals, driven by gene duplications and losses. 🔗 doi.org/10.1093/gbe/evaf165 #genome #evolution #primates
SCPP gene presence/absence phylogeny. Blocks represent genes within the SCPP locus, color-coded by functional relevance: enamel (purple), milk (blue), saliva (yellow), and genes implicated in all three functions (red). The animal phylogeny is shown on the left with species silhouettes. Two primate species (baboon and green monkey) are depicted placing blocks representing saliva-related genes at the points in evolution where these genes emerged. Imagine designed in BioRender.
